Want to get a bit more audio quality out of mp3's?

Try this setting for the equalizer.

These settings/pics are for iTunes, but I tried it in Windows Media Player and it did seem to give the mp3's a bit more life.

" Open the equalizer, and from the pop-up menu, select “Make Preset.” Call it “Perfect,” because it is, and set the following levels, from left to right (skip the Preamp section):

db +3, +6, +9, +7, +6, +5, +7, +9, +11, +8 db"
